Question { Bhel, 108769 }
what do you mean by 1 ton in AC`s
Answer
The cooling produced by melting of 1 ton of ice in a day is
taken as unit of refrigeration (in tons). Now unit of
refrigeration used in S.I. System is KW.
1 ton of refrigeration
= mass of ice x latent heat of ice / 24 hrs
= 900 kg x 335 KJ/Kg ( one short ton = 900 kgs )
------------------
24 x 3600 secs
= 3.4895 KJ/Sec
say 3.5 KJ / Sec = 3.5 KW
that is 1 ton of refrigeration = 3.5 KW
